Manzhu Shahua planting: can be cultivated in open field, greenhouse potted, framed cultivation or hydroponic potted plants.
The other side of the flower likes to scatter light, does not like glare, so the light is not too strong. The requirements of the other shore for the soil are usually not required. However, it is a southern flower after all, so the soil is acidic, a bit sandy, breathable and permeable. The flowers on the other side have ornamental value all year round, with leaves without flowers and flowers without leaves.
Lycoris is highly adaptable, the bulbs are dormant, and the north needs potted plants. The Lycoris planted at the end of May should also bloom. Suitable time for cultivation in the north: It should be planted in spring (April-May). Most varieties prefer a warm climate, the highest temperature does not exceed 30 ° C, the average temperature of 24 ° C, suitable for Lycoris. After 10 days of sowing, the roots grew vigorously and the leaves grew out of the ground. The average daily temperature in winter is above 8 °C, and the lowest temperature is 1 °C, which does not affect the growth of Lycoris. Watering should not be too much, otherwise it will cause its roots to rot.
Manzhu Shahua cultivation:
The small bulbs around the main ball are peeled off for breeding. The roots of the main ball are repaired and dried for two days. After the wound is dry, it can be planted. When covering the soil, make the top of the ball out of the soil. Potted plants are grown for 3 years, can bloom in large balls (with a diameter of 7 cm or more), can be planted in a pot, or can be planted in a large pot of 3 to 4 balls. To plant shallow, make the ball 1/3-1/2 on the soil. After watering the basin, the soil is slightly moistened. Water the water after it has been sent. Apply liquid fertilizer once every half month. Watering can be stopped when the leaves are thickened and ripe in autumn.
After 2 to 3 months, after germination, turn over the basin or replace the potting soil. The culture soil can be prepared by mixing 2 parts of peat, 2 parts of garden soil and 1 part of perlite, and adding a small amount of base fertilizer. In the summer dormant period, there should be less watering, and the spring and autumn should always keep the soil moist. During the growing season, the pancake water is applied once every half month. Lycoris is half-yin, avoiding direct sunlight in summer, and keeping it in the semi-yin in spring and autumn. Strictly control watering during the winter and stop fertilizing. Fourth, post-flower treatment and pest control Lycoris should be cut off after flowering to reduce the loss of nutrients. The management of Lycoris radiate is extensive. Common diseases include anthracnose and bacterial soft rot. The bulbs are soaked in 0.3% copper sulfate solution for 30 minutes before planting, washed with water, dried and planted. Spray 50% carbendazim WP 500 times every half month. In the early stage of the disease, spray with 50% benzoate 2500 times solution.
Manzhushahua cultivation environment requirements:
The planting depth should not be too deep, just as the top of the bulb is just buried in the soil. Soil quality requires well-drained sandy soil or loose culture soil, acidic soil, apply proper amount of base fertilizer and water after cultivation; during the nutrient growth period, it should be regularly filled with water to keep the soil moist, but not water. The bulbs rot. The right amount of water must be supplied from the 20th day before flowering to the flowering stage, so that the flowering is neat and uniform, and the flowers are easy to maintain.
Common pests of Manzhushahua:
1. Spodoptera larvae, mainly larvae endangering leaves, flower buds, fruits, eating mesophyll, biting buds, seeds, generally in the end from the end of spring to November, 5% Regent suspension 2500 times liquid, 10,000 Ling 1000 times liquid control.
2. Lycoris radiata, the plants invaded by its larvae, usually the leaves are hollowed out, and can directly feed on the inside of the bulbs. The affected areas usually leave a lot of green or brown feces, often pay attention to the back of the leaves, with or without arrangement. Neat eggs are found to be removed immediately. In the prevention and control, it can be combined with winter or early spring to remove the overwintering insects and reduce the number of insects. When it occurs, spray 1500 times of Pharmacy and 800 times of phoxim emulsifier, choose to spray when morning or evening larvae come out. The control effect is better.
3. Hummer, red body, mainly sucking nutrients at the bulbs and leaves, leading to chlorosis, especially after fruit ripening, can use 25% imidacloprid 3000 times solution, 70% Emerald 6000-10000 times solution Rotate spray control.
4. Hey, after the discovery, the use of phoxim or trichlorfon should be used in time for prevention and treatment.
